Definitions
- the embodiments disclosed herein are related to systems, methods, and computer readable medium for simultaneous imaging of different physical properties of an examined medium from the simultaneous joint inversion of multiple datasets of physical field/signal measurements and for digital enhancement and restoration of multiple multidimensional digital images.
- at least one component of at least two physical fields and/or signals or at least two images produced by at least two sensors of corresponding physical fields and/or signals, generated by natural or artificial (controlled) sources, placed at some proximity of the examined medium are measured.
- the observed data and/or images are recorded by a corresponding recording device.
- Another embodiment of the method disclosed herein can be applied in medical imaging for fusion multiple datasets, such as x-ray, magnetic resonance, magnetic tomography, ultrasound, electrical, and radionuclide data.
- At least one embodiment of this method can be used for geosteering.
- the simultaneous imaging of different physical properties of an examined medium from the joint inversion of observed data from multiple geophysical field measurements may be achieved using the processor 19 of FIG. 2, which may include, for example, a central processing unit, a storage system, and a communications system.
- the processor 19 may be distributed across one or more processors.
- At least two images produced by at least two sensors of corresponding physical fields and/or signals, generated by natural or artificial (controlled) sources, placed at some proximity of the examined medium are measured, or by the same sensors but at different time moments.
- the images recorded by a corresponding recording device are determined.
- a nonnegative joint entropy functional determined as a joint weighted average of the logarithm of the corresponding density of at least two images and/or their attributes is determined.
- Smoothing or focusing stabilizing functionals for producing smooth inverse images or images with sharp boundaries are also determined.
- a parametric functional defined as a linear combination of misfit functionals for at least two datasets, smoothing or focusing stabilizing functional, and the joint entropy functional is constructed. Deblurred images, which correspond to the minimum of the parametric functional, are determined by solving a minimization problem for the parametric functional using linear and/or nonlinear optimization methods.

Abstract
Est décrit un procédé pour l'imagerie simultanée de différentes propriétés physiques d'un milieu examiné à partir d'ensembles de données multi-physiques et pour l'amélioration et la restauration numériques de multiples images numériques multidimensionnelles. Le procédé introduit une entropie conjointe non négative déterminée en tant que moyenne pondérée conjointe du logarithme de la densité correspondante des paramètres de modèle et/ou des images et/ou de leurs attributs. Les mesures d'entropie conjointe sont introduites en tant que contraintes supplémentaires, et leur minimisation conduit à l'application de l'ordre et de la cohérence entre les différents paramètres de modèle et/ou les multiples images et/ou leurs transformées. Le procédé ne nécessite pas de connaissance a priori concernant des relations spécifiques physiques, ou analytiques, ou empiriques, ou statistiques entre les différents paramètres de modèle et/ou les multiples images et leurs attributs, et le procédé ne nécessite pas non plus de connaissance a priori concernant des relations spécifiques géométriques ou structurelles entre différents paramètres de modèle, différentes images, et/ou leurs attributs.
